Just wanted to echo and reinforce the comments that Justin Wilson made about every router that participates in OSPF needs to have the exact same version on it. He is 110% correct. This is not brought up a lot but is the SINGLE biggest factor in achieving OSPF and overall stability between the routers. I probably have this conversation at least once a day with a client WISP about setting a common version between all the OSPF routers.
The bugfix versions are good, I usually recommend 6.32.4 or 6.36.4 bugfix for production routers and never the latest unless there is a feature or fix you must have.

It's nothing close to "blowing up" the logs, but troubling nonetheless. And yes, it didn't start happening until we upgraded, probably to 6.36.x. Just another data point.
